PELLETS
Wood pellets are manufactured by hot-extruding compressed sawdust which is produced during the processing of natural dried
wood (without paints). The compactness of the material is guaranteed by the lignin contained in the wood itself and allows pellets
to be produced without glue or binders.
The market offers different types of pellets with characteristics that vary according to the wood mixtures used. The diameter varies
between 6 and 8 mm, with a standard length ranging from 5 to 30 mm. Good quality pellets have a density that varies between
600 and over 750 kg/m3, with a moisture content that ranges from 5% to 8% of its weight.
Pellets have technical advantages besides being an ecological fuel, as the wood residue is used completely, thereby achieving
cleaner combustion than that of fossil fuels.
Good-quality wood has a calorific value of 4.4 kW/kg (15% moisture, after about 18 months of seasoning), whereas that of pellets
is 4.9 kW/kg. To ensure good combustion, the pellets must be stored in a dry place and protected from dirt. Pellets are usually
supplied in 15 kg bags, therefore, storing them is very convenient.
Good quality pellets guarantee good combustion, thereby decreasing harmful emissions into the atmosphere.
